Guys, what u don't understand is that Xbox 360 and wii have custom processors (xbox'es is 3-core which is a problem) based on the PPC instruction sets, NOT real, off-the-shelf PPC cpus. In theory OS4 should work but there could be a ton of incompatibilities caused by the special design of these cpus. After all, the freescale 405 cpu is PPC too, but OS4 (the public version anyways) doesn't run on it. Things are not as simple as saying, "it has PPC, it will boot OS4!", and we're not even touching aspects like system-logic support, firmware, graphics....
